Technologist, Contamination Control Engineering

About the role

Western Digital is seeking a detail-oriented and analytical Technologist, Contamination Control to join its team in Amphoe Si Maha Phot, Thailand. The role monitors, analyzes and controls contamination levels across operations, maintaining high standards of cleanliness and product integrity while complying with industry regulations and organizational protocols. It calls for a systematic approach to problem-solving and a commitment to continuous improvement.

Key responsibilities

• Lead contamination prevention initiatives to improve product cleanliness, manufacturing yield, reliability and customer satisfaction.
• Develop and continuously improve contamination control strategies, engineering standards, monitoring programs, specifications and best practices across products, processes, equipment and cleanroom environments.
• Drive Real-Time Particle Monitoring (RTPM) and environmental monitoring performance by reducing false alarms, minimizing contamination events and implementing predictive monitoring using particle sensors, airflow monitoring and data analytics.
• Lead complex contamination investigations (yield loss, customer complaints, reliability failures, manufacturing excursions) using 8D, FMEA, DOE, SPC, Fishbone and statistical analysis.
• Identify contamination sources and implement corrective and preventive actions (CAPA).
• Optimize cleanroom performance through airflow engineering, environmental control and advanced monitoring technologies.
• Evaluate, qualify and deploy advanced contamination control technologies, cleaning processes, filtration systems, automation and analytical solutions.
• Analyze contamination trends and manufacturing data to recommend improvements and develop contamination control roadmaps aligned with business strategy.
• Mentor engineers and technicians, and collaborate with cross-functional and global teams, preparing technical reports and business cases for senior management.

Required profile

• Bachelor's degree in engineering, Materials Science, Chemistry, Physics, Environmental or Mechanical/Chemical Engineering or a related discipline; Master's or Ph.D. is an advantage.
